I do not think that marriage was the only option they had because they JUST met each other and it was love at first sight. They could have waited to get married , but instead they rushed into it thinking that it would stop the family feud when it clearly didn't. Because the two,Romeo& Juliet , wanted to get married to each other so soon , family members were getting killed by one another , and family was going against family. When Juliet tells her parents that she'd rather get married to a montigue instead of paris , her father goes against her and tells her that if she does not show up to get married to paris , he does not want anything to do with her. if she did not rush into getting married to romeo , family members would not be getting killed , and her family would not go against her
